Lexus IS 250 to get new turbo four?

"All show, no go." That's how I described the 2014 Lexus IS 250 F Sport that you see above, when I reviewed it back in November. Don't get me wrong, there's a lot to like about the new IS, but the 204-horsepower, 2.5-liter V6 in the IS 250 is not on that list. In my review, I suggested that Lexus ought to get on the bandwagon of offering a small-displacement, turbocharged, four-cylinder engine in its base IS (like its rivals), and now the folks at Motor Trend are furthering that discussion.
Lexus pulled the wraps off its new NX 200t crossover at the Beijing show recently, and it'll be the first vehicle in the company's lineup to use a brand-new - you guessed it - 2.0-liter turbo-four. With 238 horsepower and 258 pound-feet of torque on tap, that represents a healthy increase over the 204 hp and anemic 185 lb-ft currently being offered with the 2.5-liter V6, and we imagine the fuel economy gains will be rather significant, too. For comparison, the Lexus' four-pot power numbers are very close to the 240 hp and 255 lb-ft offered in the same-sized engine that BMW uses in the 328i.
Motor Trend also posits that Lexus may consider changing the base IS' name from 250 to 200, or perhaps 200t, to properly reflect the new engine's displacement. Of course, that's assuming Lexus doesn't pull a BMW or Mercedes-Benz, and no longer has its alphanumeric names properly reflect the size of the powerplant found underhood.

Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."
